This innovative exhibition offers insight into how Darwin developed his evolutionary idea by producing a replica of his "sand walk" – a route he trod every day with his terrier. On this, he observed nature and reflected on his experiments and travels on the 'Beagle'; piecing his theory together. This playful idea complements the rich collection of letters owned by the British Library and revealing the private Darwin – a humorous, emotional and charmingly modest man.
